Summary: Antibacterial plasma electrolytic oxidation coatings incorporating partially oxidized Ag particles on pure Mg effectively inhibit the growth of S. aureus, with the antibacterial efficiency mainly dependent on the Ag concentration in the layer. The antibacterial rate of the coating can reach 99% and remain stable when sufficient Ag particles (above 1 wt%) are incorporated.

Summary: Mg and its alloys are suitable choices for implant materials due to their biodegradability and biocompatibility features. However, the high electrochemical activity of these materials results in fast degradation and severe corrosion. The use of plasma electrolytic oxidation (PEO) surface modification technique can enhance the antibacterial activity of Mg and its alloys while maintaining their corrosion protection properties.

Summary: A ZnO/Zn(OH)(2) hybrid coating was fabricated on pure Zn surface through plasma electrolytic oxidation (PEO) to investigate the effect of PEO treatment on the degradation behavior of Zn and Zn-based materials. The degradation effects were studied through immersion tests in simulated body fluid (SBF) and Hank's solution. The results showed that PEO treatment accelerates the degradation of Zn and the corrosion products mainly consist of Zn(OH)(2), ZnO, Zn-3(PO4)(2), and Ca-P matters. PEO-treated Zn exhibited good in vitro biocompatibility and enhanced antibacterial properties, making it promising for orthopedic implants.

Summary: Plasma electrolytic oxidation (PEO) coatings are widely used and their modifications are usually targeted towards specific applications. However, the evaluation of PEO coatings often focuses solely on the intended application without considering other potential uses. Electrochemical impedance spectroscopy (EIS) is a powerful technique for assessing PEO coatings, as it can analyze their structural, morphological, chemical, and electrochemical properties. Therefore, a comprehensive review describing the versatile behavior of PEO coatings using EIS is essential for researchers and engineers to evaluate PEO coatings beyond their intended applications.

Summary: This study evaluates the tribological and corrosion behavior of nano-structured CrN/CrAlN and CrCN/CrAlCN coatings applied on 430 stainless steel. The coatings were characterized using X-ray diffraction, field emission scanning electron microscopy, and nano-indentation techniques. The adhesion of the coatings to the substrate was also evaluated. The results showed that CrCN/CrAlCN exhibited the lowest friction coefficient and better resistance against corrosion compared to the CrN/CrAlN coating, which can be attributed to its higher hardness, denser structure, lower surface roughness, and low wettability.

Summary: This study investigated the tribological and corrosion performances of as-deposited and annealed CrN/CrAlN multilayer coatings on 304 stainless steel substrates deposited by cathodic arc evaporation process. The results showed that annealing led to the decomposition of CrN into Cr2N. Additionally, the surface roughness and wettability of the annealed samples increased as the annealing temperature increased. The hardness decreased due to the increase in crystallite size. The sample annealed at 400 degrees C exhibited the lowest wear rate and the specimen annealed at 700 degrees C showed the highest corrosion resistance.

Summary: This work investigated the influence of sealing treatment on the structural and electrochemical properties of AZ31 Mg alloy coated by plasma electrolytic oxidation (PEO). The results showed that sealing in hot solutions triggered hydration reactions and promoted the incorporation of Co3O4 into the coating. In contrast, sealing in cold solutions resulted in less compact coatings. A nearly fully sealed coating with high electrochemical stability was successfully formed in the hot solution containing 1 gr of cobalt nitrate hexahydrate.

Summary: The formation of inorganic-organic hybrids (IOH) on metallic substrates plays a crucial role in improving their structural and functional features. In this study, an organic coating (OC) consisting of coumarin-3-carboxylic acid (3-CCA) and albumin (ALB) was grown on an inorganic layer (IC) produced by plasma electrolysis of AZ31 Mg alloy. The synergistic actions between OC and IC resulted in the formation of a flake-like structure that sealed the structural defects of IC and provided chemical protection and photocatalytic performance.

Summary: The wear and electrochemical behaviors of CrN/AlCrN multilayered coatings annealed at different temperatures were investigated in this study. The deposition of the coatings was done using the cathodic arc evaporation technique. Characterization techniques such as SEM, field emission SEM, X-ray diffraction, and Rockwell-C indenter were used to analyze the coatings and the interdiffusion between the layers. The results showed that the interdiffusion of the layers increased with increasing annealing temperature, leading to changes in mechanical and corrosion properties of the coatings.

Summary: This study investigates the effect of iron nitrate on the corrosion behavior of a 6061 Al alloy treated with a plasma electrolytic oxidation coating. PEO coatings were applied on Al alloy samples using an alkaline-aluminate electrolyte with and without iron nitrate. The presence of iron nitrate resulted in the integration of Fe2O3 particles into the coating layer and reduced the porosity and size of micropores formed during plasma activity. As a result, the coating formed in the electrolyte with iron nitrate exhibited superior corrosion resistance compared to the one without iron nitrate.

Summary: This study investigates the effect of incorporating anatase TiO2 nanoparticles at three different concentrations into ceramic-like oxide plasma electrolytic oxidation (PEO) coatings on pure titanium substrate on their friction and wear behavior in simulated body fluid (SBF) aqueous solution. The wear performance of the coatings was characterized using a ball-on-disk friction and wear tester, and the morphology and dimensions of wear tracks were analyzed by scanning electron microscopy (SEM) and 2D depth profilometry. The results showed that the concentration of TiO2 nanoparticles strongly influenced the coefficient of friction, wear volume loss, and wear rate of the coatings, with coatings containing TiO2 nanoparticles exhibiting lower COF, less wear volume loss, reduced wear rate, and improved wear resistance compared to coatings without TiO2 nanoparticles. The coating with 3 g/L of TiO2 nanoparticles demonstrated the best wear protection properties among all the coatings tested.

Summary: WO3 nanoparticles were grown hydrothermally on porous titania (TiO2) PEO-coated on Ti in an alkaline electrolyte using pulsed direct current mode. The hydrothermal parameters including precursor concentration, temperature, and time were optimized to achieve the best photodegradation of methylene blue mediated by the PEO/HT hybrid coatings under visible illumination. The improvement in photocatalytic performance was attributed to the participation of more WO3 nanoparticles and the expansion of the light absorption range of TiO2 up to the visible light range.
